INO80 chromatin remodeling complex in Drosophila melanogaster
The INO80 complex is an ATP-dependent chromatin remodeler of the INO80 subfamily that slides nucleosomes and positions the +1 nucleosome at promoters, and contributes to transcription regulation and DNA repair. In Drosophila it contains the Ino80 ATPase, the AAA+ ATPases Pontin and Reptin, actin and the actin-related proteins Arp5 and Arp8. FlyBase also places the Polycomb group DNA-binding protein Pho (the YY1 homolog) in the complex, consistent with a role of INO80 in recruiting Polycomb proteins.
Grouping of actin, Arp5 and Arp8 together is a coarse simplification; in yeast Arp8 and actin bind the HSA region while Arp5 binds the ATPase. Pho is included because FlyBase lists it as an INO80 subunit; it is also modelled in the PhoRC part of dmel_polycomb_group_complexes. FlyBase groups realized by this module: INO80 (FBgg0000291). Participants were generated from the FlyBase gene-group membership and mapped to UniProtKB by projects/FLYBASE_GENE_GROUPS/generate_modules.py from module_specs/dmel_ino80_complex.yaml. None of the member genes has a gene review in this repository yet.

Function consistency and core coverage
0 gene-function check(s) reflected in core functions · 0 conflict(s) · 1 evidence or coverage gap(s) (1 comparison(s))
Retained noncore functions are reported separately; they do not require promotion to core functions. Support from representative genes does not establish conservation across the whole family. Missing reviews or identifiers leave a claim unverified.
